Why it works: Parsley and pepper match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Sweet-breads with Mushroom Sauce
Ingredients
Directions
Prepare the sweetbreads
Soak the sweetbreads in cold salted water for 1 hour.
Remove all stringy parts and soak in clear cold water briefly.
Dry the sweetbreads with a towel.
Dip them in beaten egg and then in fine bread crumbs.
Fry and serve
Fry in equal parts lard and butter until brown.
Place the fried sweetbreads in a hot dish.
In a saucepan, combine cream or milk, butter, parsley, salt, and pepper.
Add a little thickening and the can of mushrooms.
Bring to a boil and pour the sauce over the sweetbreads.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sweetbreads
- Provide the tender main protein that the dish is built around.
- Beaten egg
- Binds the fine bread crumbs to the sweetbreads so the coating adheres while frying.
- Fine bread crumbs
- Form a crisp, golden-brown coating when fried in fat.
- Lard and butter
- Fry the coating, promoting browning and adding rich flavor.
- Cream or milk
- Forms the body of the sauce, adding richness and a smooth texture.
- Thickening
- Thickens the sauce so it coats the sweetbreads rather than running off.
The step that matters
Drying the sweetbreads before coating. Surface moisture keeps the egg and crumbs from sticking evenly and steams the coating, so it fries unevenly instead of browning crisply.
Swap the parsley
How well each one fits the dish's main ingredients (egg, bread, butter, cream, pepper, mushroom):
- Nutmegfits about as well
- Parsleythe original
- Thymefits about as well
- Tarragonfits less well
Fit is the average pairing score against egg, bread, butter, cream, pepper, mushroom. Candidates are from the same food group and used in at least 100 recipes.
